As a layperson in both history and science, perhaps Sutton should leave science to the scientists and history to the historians? "Started his career of doubting when he was very young" tells me he probably was one of those insufferable people who sit in the back of a college class and try to correct the professor, who care more about correcting others and "being right" than "not being an insufferable ass." This is typical of the online "skeptic" community. "Skeptics" generally have little background in the fields they criticize, and they see opinions and observations as things that need "debunking" rather than engaging in conversation with researchers or questioning the importance of debunking a myth. It's no wonder that they're often wrong themselves, since they lack any understanding of nuance.
Are you saying that correcting people is not important and they should just be left to be wrong?
